An air puck of mass 0.102 kg is tied to a string
and allowed to revolve in a circle of radius
1.13 m on a horizontal, frictionless table. The
other end of the string passes through a hole
in the center of the table and a mass of 0.43 kg
is tied to it. The suspended mass remains in
equilibrium while the puck revolves.
The acceleration of gravity is 9.8 m/s2 .
What is the speed of the puck?
Answer in units of m/s.
i figured out that the tension in the string is 4.214 N.
Please, no rounding. huge decimals expected..
thank you :D
